Helium-Neon Laser 1 Introduction The Helium-Neon Laser, short HeNe-Laser, is one of the most common used laser for allignement, reference laser and optics demonstrations. Its most used wavelength is at 632.8nm (red). It also has lasing transition in IR, orange and green. This experiment will make you familiar with basic
This helps to create a state of population inversion between the levels E4 (or E6) and lower energy levels E5 and E3. Therefore the purpose of He atoms is to help in achieving a population inversion in the Ne atoms. E6 to E5 with laser wavelength of 3.39 μm or 33900 Angstroms. E6 to E3 with laser wavelength of 6328 Angstroms.

The Helium-Neon (HeNe) LASER The active laser medium is a gaseous mixture of He & Ne atoms, in a roughly 10:1 proportion. The gas is enclosed in a cylindrical quartz DISCHARGE tube sealed at each end by a mirror to form the optical cavity. Pumping is done via an electrical discharge (A GLOW DISCHARGE) created between the electrodes.
This laser pulse stimulates the electrons to drop to their lower, or ground, energy states and emit a laser photon of exactly the same wavelength. An optical switch traps the low-energy laser pulse in the main amplifier for four passes through the laser glass slabs. Mirrors at both ends of the glass amplifier cause the photons to travel back ...

He-Ne Gas laser consists of a narrow discharge tube of bore glass or quartz of length 10 to 100 cm with a diameter of the order of 5mm to 10mm. He-Ne Laser construction The tube is Filled With a mixture of helium and neon gases, approximately in the ratio, 85 % a helium and 15% neon, contained at low pressure (typically ~2-3 torr).
To understand the significance of a population inversion to HeNe laser action, it is useful to consider the processes leading to excitation of He and Ne atoms in the discharge, using the simplified diagram of atomic He and Ne energy levels given in Fig. 3. A description of the rather complex HeNe excitation process can be given in terms of the ...

Common laser types For many years, the most common CW laser was the helium neon laser, or HeNe. These low-power lasers (a few milliwatts) use an electric discharge to create a low-pressure plasma in a glass tube; nearly all emit in the red at 633 nm. In recent years, the majority of HeNe applications have switched to visible laser diodes.
